Burnie rocked up to KGV prepared and left the Southern Magpies in a daze.

By three-quarter-time the Dockers had built an unassailable 59-point lead before they let their foot off the gas in the last quarter to win 14.15 (99) to 11.5 (71).

Many were left to question whether their reign as a TSL powerhouse was over after just one triumph from the opening five rounds.

But the men from West Park are now unbeaten through five matches and the 28-point victory against Glenorchy on the weekend sees the club occupy fourth position on the ladder.

"We were really good right from the outset," Burnie playing coach Luke Shackleton said.

"We went down there ready to play and for the first three quarters we busted our guts out.

"We won the ball in close and then we took over with our run and spread.

"And one thing we were able to do was put on scoreboard pressure. That wasn't there at the start of the season, but over the last month or so we've taken our chances and applied plenty of it."

Veteran Kade Munday led from the front and was shown good support from the likes of Rudy Barrett, Jason Laycock and Brad Harvey.

Despite the tantalising option of playing Burnie utility Nick McKenna on the league's leading goalkicker, former Brisbane Lion Aaron Cornelius, he played the majority of the game up forward, where he finished with three goals.

"He's just a massive presence. He gets those long arms up there and he's pretty hard to spoil because he's a strong unit as well," Shackleton said of McKenna.

"We're lucky that we've got those young tall defenders to cover him too. They're still learning the game, but they're holding up pretty well and it allows us to mix it up."

The competition has a bye this week due to the Tasmanian state game against the NEAFL.

Six Dockers players are a chance to pull on "the map", but Devonport's only player to be selected in the initial 40-man squad, defender Klay Griffiths, will not be considered after badly injuring his right knee in Saturday's win over North Launceston.
